Application filed April 16, 1918. Serial No. 761,450.

T 0 all whom it may concern Be it known that I WILLIAM G. CARR, a citizen 'of'the United states, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Impro lements in Trucks, of which the folgi is a specification.

This invention relates to certain improvements in trucks and primarily to self-pro-- .and also beneath the flat floor of the truck.

Another feature consists inthe arrangement of a box-like compartment for a storage battery or other propelling mechanism at one end of the truck frame and attaching a short supplementary end platform to the lower end of the box which projects later? ally therefrom forming a support upon which the operator is adapted to stand, the improvement also consisting in attaching a starting, stopping, reversing, speed-changing and steering elements to the box near the upper end thereof and within convenient reach of the operators hands. I

*Another feature consists in arranging a folding frame extension at one end. of the truck frame opposite the box or compare ment "for the storage battery or'other propelling medium, said folding frame extension being adapted to be placed either in up right position to constitute a vertical end gate at one end of the main frame or to be turned down into a horizontal position to form a prolongation .ofthe truck frame and thereby provide additional supporting surface, and in attaching to said folding frame extension a second set of starting, stopping, reversing, speed-changing and steering elements so that the truck may be operated equally well froni either end.

The invention also relates to certain. de-

tails ofconstruction, which will be hereinafter described, reference being hadto the accompanying drawings in whlch a pres ferred'adaptation of'the invention is shown. 1 g g cated on the accompanymg drawings by the Figure 1 is a top plan view of the improved Specification of Letters Patent.

Fig. 5 is an enlarged detached edge view of the brake band and its operating connections and levers. Fi 6 is an enlarged detached side view of the brake. band and its operating connections and levers.

In referring to the drawings in detail, like numerals designatelike parts in the adaptation of the invention shown.

The.main' frame of this improved truck preferably consists of two longitudinal side beams, 1 and 2 of channel iron, and a series of transverse beams extending between and connecting the longitudinal side beams. The

transverse beams comprise an end beam, 3,

an intermediate beam, 4, and an end beam, 5. Besides these connecting transverse beams a fairlywide, fiat support, 6, is extended transversely across between the ends of the longitudinal beams being secured thereto by bolts or other fasteners, 7. This fairly wide, flat transversely extending support forms a support at one end of the truck upon which the operator is adapted to stand. Two axles, 8 and 9 are supportedin depending boxes 10 and 11, attached to the longitudinal beams, as shown in Figs. 1, 2 and 3. A rotary electric motor, 12, is fastened in suspended position by bolts, 13, to a cross bar, 14, which extends between and is de tachably attached to the longitudinalbeam, as shown in Fig. 1. A counter shaft, 15, is journaled in bearings, 16, attached to the longitudinal side beams,- as shown in Figs. 1, 2 and 3. The axles, 8 and 9 are of a stationary character, and have their outer ends projectin beams.

beyond the longitudinal side u-pporting wheels are rotatably. I

mounted on the outer projecting ends of the axles and, are four in number. Two of the the truck, while the other two'rotatefr'eelyw and are so constructed that they may be turned to steer thef'truck.

The propellinglpair of wheels are indi numeral,- 17, and the free-running steering wheels by the numeral, 13. In ordertliat the steering wheels mayb'e' turned to steer the truck, portions 19 of the outer end of the axle, 9, are formed separately from the xle pr p r. edat 'eieed or i eeetedt tfih'e' sameby p'votal 'ioiiits, 20, assnown in i a 1- I I i The steering is accomplished by means of angul r bars, 21,-which' are connected rigidly at; in ternaediate points .to the short pivotal portions, 19, and at their inner ends'to 10 1+ gitl dinal connecting rods,22.' Two of the angular bars, 21, are employed, 'one being connected :to each of the portions," 19, and two connecting rods, 22, are-also employed, one of said connecting rods being attached at its inner .end by a movable joint, 23, to the inner end of one .of the angular bars, 21, and having its outer end extending to one'end of the truck and attached to the operating handle, 24. The other connecting rod,- 22, is connected by a similar movable joint, 23, to the inner end of the other an gular bar, 21, and extends to the opposite end of the truck where it is connected to a similar operating'handle, 24.' From this it will be noted that thetruck maybe steered equally well from either end.

The means for and manner of starting, stopping, reversing and changing the speed of the truck is as follows :A boxor compar' tme'nt, 25, is locatedat one end of the ice;

truck and is of a fairly narrow vertical form' being arranged transversely across' the ends andforming a housing for a storage battery, 26, .a support for the various operating handles and levers and a'verticalprojecting end for .the truck platform. The storage 2 40 battery, 26, is connected by a'series of wires, 27, to an electric controller, 28, and the electric controller, 28, is inturnconnected by'a series of wires 29, to the electric motor, 12. A resistance element, .30 is attached to one of thetransverse beams of the truck frame and is connected by wires, 31, to the controller andby wires, 32, and 33, to two slightly separated metal pieces, 34, and 35,

- mounted on a strip of insulating material, 36, secured to the truck frame. The axle of the motor, J 12, is connected to the counter shaft, 15, byi'a'chain' and sprocket gearing, 37, as shown in Figs. 1 and 2, and the outer projecting end of the counter shaft is likewise connected by a chain and sprocket gearing, 38, to the propelling wheels of the truck, as shown in Figs. 1- and 2.

. A brake is arranged on the counter shaft and is preferably constructed 'as'shown'in Figs. 1, 2, 5. and 6, This brake consists of a disk, 39, which is mounted on the counter shaft and a brake band,- 40, encircling said disk. The brake band is pivotally 'sup.-.

L apivot element, 41, and isadapted to. be Referring toported at one end from the truck frameby the frame and at the opposite end to an extension, 47, attached to the crank.

,A means for manually releasing the brake I is'provided which is arranged tobe operated from either end of the truck. This means consists of foot treadles, '48, located at opposite ends of 'the truck and connected-to the outer ends of connecting rods, 49, which extend to and connect at their inner ends to an extension, 50, of the crank, '44, as

shown in Fig. 1.

The controller is opera from either end to vary the speed or reve the direction'of travel-of. the truck. This is accomplished by means oflevers 51, to which handles, 52, are detaohablysecured, as shown in Fig. l. A -lever,, 53,- is pivotally mounted on one of the frame members as shown in Fig. 1 and has one end thereof connected by a connecting-rod, 54, to a gear mechanism, 55, for turning the controllers A connecting rod, 56, extends from the opposite end of .the lever, 53, and is connected to the lever, 51 located at the opposite end of the truck. The lever, 51', located at the opposite end of the truck is likewise connected to the lever, 53, by a connecting rod, 57, said connecting rod, 57, bein'g'connected to said 'lever at a point in proximity to the lever joint thereof'to the lever, 54.

Means-is provided by which the electric circuit is automatically broken by the setting of the brake and is automatically com pleted by the releasing of said brake. This improved means forms a part of the subject matter of a companion applicationof even date, so that but a brief description of the same will be given herein. A connecting .rod, 58, extends from the crank, 44, being connected at itsinner end to said crank and at its outer end to a slide, 59. A I floor or platform, 60, whichis preferably formed (if-matched boards is arranged upon the truck frame, as shown in Fig. 2. A laterally projecting end platform or sup port, 61, for the operator is attached to the lower end of the box, 25, being bolted therei to by bolts, 62, as shown in Fig. 2. A' folding end extension is arranged at the end of the truck opposite the box, 25, and is adapted to be turned up into vertical position, as shown in full. lines, in Fig- 2, or down in horizontal position, as shown in. dotted lines, to constitute a prolongation of the supporting platform.

Fig. 4 it. will be noted that magma K 7 the end extension isa skeleton frame composed of longitudinal members, 63, and

' transverse members, 64. The lower ends of the longitudinal .side members, 63, are pivoted to the main truck frame by pivot pins, 65, as shown in Fig. 9., and to lock the end extension in its vertical position, jointed connecting bars, 66, are pivoted. at one'end to the end extension and at the opposite end of the truck frame, as shown in Fig. 2. When the end frame extension is in its vertical position, the jointed bars, 66, are

straight and extend diagonally from the end extension to the truck frame, as shown in full lines in Fig. 2. To turn the end frame extension, it is first necessary to bend the two members of the jointed bars, 66, at their joints or connection and then move the frame extension downward into the position shown in dotted lines in Fig. 2. When the end frame extension is in a horizontal position, the members of the jointed bars, 66,

are bent nearly parallel with each other, as

shown in Fig. 2. The slide 59, is slidably mounted on the insulating strip,-86, and is adapted to be moved into'oontacting and connecting position with the portions, 35 and 36, when the brake band is expanded and the brake is released, thereby electrically completing the circuit.

The operation of this improved truck Will be clearly understood by referring to the accompanying drawings. In starting the truck, the operator first presses his foot upon one of the treadles, 48, and forces it down. This expands the brake band, releasing the brake and also moves the slide, 59, electrically completing .the circuit. It will be noted by referring to Fig.1 that the wire, 67 connects the slide to the controller so that when the slide is in contacting position with both of the portions 35 and 36, the truck is automatically started at its slowest speed in one direction. The trucks speed is varied or its direction of travel changed, in other words, reversed .by

- movement of the detachable operating handles, 52.

The truck is steered from either end by the handles '24. When it isdesired to stop, the pressure on the foot treadle 4:8, is removed permitting said treadle to move upward and the tension of the spring, 46, to

automatically set the brake. This movement also automatically moves the slide, 59, brea'king'the electrical circuit.

l/Vith this improved truck all or nearly all of theoperating mechanism is arranged and concealed beneath the floor of the truck and is supported from or between the twolongitudinal side beams, the controlling means is so arranged that the truck may be started,

stopped, reversed or the speed varied from either end of the truck.

I claim,

1. A truck of the class described consisting of a frame, a platform or floor on said frame, a vertical box at one end of said frame, a folding end extension at the opposite end of said frame, a set of controlling elements attached to the vertical box, a secondset of controlling elements attached to the folding end extension, operating mechanism arranged beneath the platform or floor, and a storage battery in the vertical box.

2-. In a truck of the class described a frame, a vertical box arranged at one end of said frame, forming an inclosing housing for a storage battery, a transverse gate or wall for the truck end and a support for 4:. In a truck of the class described, av

frame having a box at one end and-a pivotal end extension frame at the opposite end, operating mechanism supported from the frame, a storage battery in the box, and controlling elements for said; operating mechanism arranged in two sets with one set attached' to the box and the other set attached to the end frame extension.
